GLAZIERS INSTRUMENT.

Specification of Letters Patent.

Application filed April 22, 1908.

Patented May 18, 1909.

Serial No. 428,506.

T 0 all whom it may concern:

Be it known that I, JAMEs W. TUCKER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Glaziers Instruments, ofwhich the following is a specification.

My invention relates to improvements in glaziers instruments.

The object of this invention is to provide an improved construction indevices of this character.

It further designs to combine a cutter and oiler with a holder intowhich said cutter and oiler may be folded when not in use but which maybe readily extended and brought into operative position.

To such end this invention consists in cer tain novel features ofconstruction and arrangement, a description of which will be found inthe following specification and the essential features of which will bemore particularly set forth in the claims.

The invention is clearly illustrated in the drawings furnished herewithin which- Figure 1 is a perspective view of the device. Fig. 2 is alongitudinal section thereof. Fig. 3 is a perspective view of the wickholder. F ig. 4 is a detail section taken on line 44 Fig. 2 and Fig. 5is a cross-section of a slightly modified form of handle or cas- 111 Inthese views 10, is a handle preferably comprising two side plates 11,11, connected by a spring back 12 which is riveted orotherwise securedto the sides as shown at 13. This afiords a combined handle and casinghaving an open side for the folding parts of the device. A wheelcarrying blade 14, is pivoted to one end of the handle by a pin, rivetor the like 15, and a wick holder 16 is pivoted to the other end of thehandle by a pin, rivet or the like, 17. The wheel carrying blade andwick holder are each formed with a shoulder 18, adapted to abut againstthe adjacent end of the spring back 12, after the manner of the ordinaryknife-blade. The spring back also bears against projections 19 formed onthe wheel carrying blade and wick holder respectively, to hold them inopen or closed position.

The end of the blade 14 is beveled off as at 20 and a cutter wheel ordisk 21 is ournaled in the angle formed at the extreme end of the blade.The blade is forked at the end to receive the cutter wheel, and a screw21 is secured in the forked end to act as journal pin for the cutterwheel.

The wick holder is preferably in the form of a tube of rectangular crosssection and contains a piece of wicking 22 which projects slightlybeyond the end of the tube. This wicking may be made up of felt, gauzeor other like absorbent material capable of retaining a quantity of oilor other lubricant, the object of which will appear later. Notches 23are provided in the blade and holder to facilitate the o ening out ofthe same. The blade and ho der are so proportioned that when folded upthe end of the wick will contact with the end of the cutter carryingblade, and wheel, thus automatically oiling the wheel and journal. Theordinary notches 24 may be formed in the blade after the manner of theordinary glass cutter.

In Fig. 5 the handle is shown as made up of a single piece of sheetmetal bent into a form having a U shape in cross section. This forms asimple and inexpensive handle and serves to contain the blade and holderwhen folded up. If desired the cutter wheel and wicking may be secureddirectly upon the ends of the handle thus dispensing with the foldingblades.

Glaziers find it of great advantage to apply oil along the line wherethe glass is to be cut and use a brush or other device for this purpose.I have found that by providing the cutting tool with an oiling device,considerable time and labor is saved, as the wick may be dipped into theoil occasionally and drawn across the glass along the cutting line. Furthermore as the wick retains a considerable quantity of the oil, thecutter wheel and its journal are oiled by reason of their contact withthe wick when the blade and wick holder are folded. up in the handle.The journal of the cutter wheel is thereby automatically oiled quitefrequently and its durability is greatly increased. The screw connectionaffords means for the ready removal of the cutter wheel whenever itbecomes desirable to replace the same with a new one.

I am aware that various alterations and modifications oi this device arepossible without departing from the spirit of my invention and I do not,therefore, desire to limit myself to the exact form shown and described.

I claim as new and desire to secure by Letters Patent:

1. A glaziers instrument comprising a handle having a fold able tubularwick holder pivoted upon one end, and a wick insaid holder extendingbeyond the end of said holder.

2. Aglaziers instrument comprising an open sided handle having a cutterwheel blade pivoted upon one end and carrying a cutter wheel, and anoiler for said cutter wheel pivoted upon the other end, said blade andoiler being adapted to be extended into operative position or folded upwithin the handle to bring the cutter wheel and oiler into engagementwith each other.

A glaziers instrument comprising an open sided handle, having a cutterWheel blade pivoted upon one end, .an oil'er pivoted upon the other end,and :a spring back :for said handle engaging the blade :and oiler tohold them :either in operative or folded position, the blade and. o ilerbeing so proportioned and arranged that the \oiler will apply oil to thecutter wheel when the blade and oiler are folded up in the handle.

4. A glaziers instrument comprising an open sided handle having a cutterwheel blade pivoted p one end, a tubular widk holder pivoted uponv theother end, and a wick confined in said holder and extending beyond theopen end thereof and adapted to contact with the cutter wheel when theblade open sided hand le having a wheel carrying blade pivoted upon oneend, a wick holder pivoted upon the other end, and :a wick confined insaid holder, the blade and holder being so proportioned and arrangedthat the wick will contact with the cutter wheel when the blade andholder are folded up in the handle.

6. A glaziers instrument comprising an open sided handle, having afoldable' Wheel carrying blade anda foldable wiokholder, a cutter wheeljournaled in said blade and a wick in said holder, saidwh'eel :and Wickbein g arranged to abut each other when the-blade and holder :arefold-ed up within the handle:
